https://www.careers360.com/question-how-much-marks-i-have-to-score-in-jkcet-to-get-addmission-in-gcet-jammu IT matters what branch you are opting for because if you want civil it will end up under 110 rank,but if you just want to end up taking admission in gcet without any interest of branches alloted then be under 1000 rank if in general or above 1000 if you have any category and in my estimation 600 rank was of a candidate having 45 marks in total in jkcet. I think it will help you
I don't know about the cutoff but in the first round of counseling, mostly people had less than 400 Rank.
Civil was having the lowest cutoff.
The last intake in first round wae probably Rank 103 or something.
